These are honest and powerful moments because the pressure of life is squeezing these characters between the lesser of two evils. And where in a well-crafted story is pressure the greatest? At the end of the line. The wise writer, therefore, obeys the first principle of temporal art: Save the best for last. For if we reveal too much too soon, the audience will see the climaxes coming long before they arrive.

Melodrama is not the result of overexpression, but of under motivation; not writing too big, but writing with too little desire. The power of an event can only be as great as the sum total of its causes. We feel a scene is melodramatic if we cannot believe that motivation matches action.

The case for international trade is no different. It’s not mainly about creating or destroying jobs. It’s about using labor more efficiently, which is one key to higher wages.

But there is a catch: Whenever trade patterns change, some people will gain (either jobs or wages) but others will lose. The federal government could and should help them more, but it doesn’t. So Americans who do lose their jobs due to international trade have a legitimate gripe.
